Answer: The first answer is A. vertical  stretch

Step-by-step explanation: The next one is B. vertical compression

The graph of the function y = 2^x represents a vertical stretch.

The given function is y = 2^x. To determine if it represents a vertical stretch or vertical compression, we need to examine the value of the coefficient in front of the exponent which is 2. If the coefficient is greater than 1, it represents a vertical stretch. If the coefficient is between 0 and 1, it represents a vertical compression. In this case, the coefficient is 2 which is greater than 1, therefore the graph of the function y = 2^x represents a vertical stretch.

Answer: B

Step-by-step explanation:

For each year that a customer does not file a claim, their rate is reduced by 10%,

This means that every year that passes, we have a subtraction of a 10% (or 0.1 in decimal form)

And also for each yearm we have a credit of $5 awarded, this means that we have an addition of $5.

Then the relation is:

f(n + 1) = f(n) - 0.10*f(n) + $5

The correct option is B

Answer:

The length of a leg of the isosceles triangle is 50√(2

Step-by-step explanation:

Since it is an isosceles right triangle, the length of the adjacent and the opposite is the same value which is let’s say x.

Mathematically; the square of the hypotenuse equals the square of the adjacent plus the square of the opposite according to Pythagoras.

Thus;

100^2 = x^2 + x^2

10000 = 2x^2

divide the through by 2, we have;

x^2 = 10,000/2

x^2 = 5,000

x = √5,000

x = √2,500 * 2

x = 50√2

(100-9^2)/3

PEMDAS: parenthesis, exponents, multiply, divide, add, subtract

Lets' work on the parethesis first.

100-9^2

We can do the exponent first, 9^2=81, so 100-81=19

Answer:

A =222 in^2

Step-by-step explanation:

A trapezoid has an area given by

A  =1/2 (b1+b2) h  where b1 and b2 are the lengths of the bases and h is the height

A = 1/2( 21+16) *12

A = 1/2 (37) 12

A =222 in^2

The HCF of 210 and 308 = 14.

The greatest number that can divide the numbers in equal parts.

It is called as greatest common factor.

Given:

Two numbers are 210 and 308.

The factors of 308 are 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308.

The factors of 210 = 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210.

From the above factors,

HCF of 210 and 308 = 14.

Therefore, 14 is the required number.

#SPJ2

Answer: P(A∪B)=0.72. The answer is provided below.

Step-by-step explanation:

Sue travels by bus or walks whenever she goes to the shops.

Probability of (catching the bus to shop ), P(A)= 0.4

Probability of (catching the bus from the shop ), P(B) = 0.7

Both of the events A and B are independent events.

Therefore, P(A∩B) = 0.4 × 0.7

 = 0.28

Probability that Sue walks one way will be = 1 - P(A∩B)

= 1 - 0.28

= 0.72

Hence, the probability that Sue will walk at one way is 0.72

Final answer:

To find the probability that Sue walks at least one way, we calculate the complement of the probability of her taking the bus both ways. The probability of Sue taking the bus to and from the shops is 0.4 times 0.7, which equals 0.28. The probability that she walks at least one way is then 1 minus 0.28, giving us 0.72.

Explanation:

The question involves calculating the probability that Sue walks at least one way to or from the shops, given the probabilities of her taking the bus. We are given that the probability of Sue catching the bus to the shops is 0.4 and from the shops is 0.7. To find the probability of walking at least one way, we consider the complement of the event that she takes the bus both ways.

Firstly, we calculate the probability that she takes the bus both ways:

P(Bus to and from shops) = P(Bus to shops) × P(Bus from shops) = 0.4 × 0.7 = 0.28

Now, the probability that she doesn't take the bus both ways (which means she walks at least one way) is the complement of the above event:

P(Walk at least one way) = 1 - P(Bus both ways) = 1 - 0.28 = 0.72

Therefore, the probability that Sue walks at least one way is indeed 0.72, as required to show.

Answer:

62.5%

Step-by-step explanation:

In this case we have the information we need to calculate the percentage because they give us the necessary experimental probability, we only have to pass the probability to its percentage form.

We know that probability can be converted to a percentage by multiplying the value of probability by 100, like so:

5/8 * 100 = 62.5

In other words, the probability that it will arrive at that time is 62.5%

Answer:

No, there are no inscribed angle in this diagram; Option D

Step-by-step explanation:

~ Let us apply process of elimination to solve this problem ~

Option 1. This first example states firstly that m∠SRT is an inscribed angle. That is not true, by definition an inscribed angle is an angle created by two chords that share a common endpoint. Neither RS nor RT are chords, in fact they each are radii, creating a central angle instead.

Option 2. m∠RST is not created by two chords, instead by arc ST and radii RS ⇒ and I believe I am not familiar with what angle it is reffered to, if at all it is named.

Option 3. As stated before, ∠SRT is not an inscribed angle; by definition an inscribed angle is an angle created by two chords that share a common endpoint, and neither RS nor RT are chords.

Option 4. Through elimination, Option D is the only possible answer left: Answer: No, there are no inscribed angle in this diagram

Answer:

d)0 and 7 are solutions of the original equation.

Step-by-step explanation:

Let's solve your equation step-by-step.

w=√7w

Step 1: Flip the equation.

√7w=w

Step 2: Solve Square Root.

√7w=w

7w=w2(Square both sides)

7w=w2

7w−w2=w2−w2(Subtract w^2 from both sides)

−w2+7w=0

w(−w+7)=0(Factor left side of equation)

w=0 or −w+7=0(Set factors equal to 0)

w=0 or w=7

Answer:

it is 8.1

Step-by-step explanation:

if u see u round over or add 1 to the number if the number that is next to the number ur rounding is 5 or higher. and u do nothing when it is less than 5.

the tenth place is where the the zero is 0.0

and the number after is 6, so it is greater than 5, so it increases

Answer:8.1

Step-by-step explanation:

To round to the nearest tenth (the first decimal place), look at the number in the hundredth (the second decimal place) and round up or down. Since the number in the hundredths is a six, you round up.

You round down if the number is less than 5 and up if it is equal to or greater than 5.

Answer: "7 is a solution to the original equation. The value –1 is an extraneous solution."

Step-by-step explanation:

The equation [tex]x=\sqrt{6x+7}[/tex] can be solved by squaring both sides:

[tex]x^2 = 6x + 7\\\\x^2 - 6x - 7 = 0\\\\(x-7)(x+1) = 0[/tex]

We can see that -1 and 7 are solutions, but make sure they are not extraneous by substituting them in the original equation:

[tex]1 = \sqrt{-1}\\ 7 = \sqrt{49}[/tex]

The square root of 49 equals 7, but the square root of -1 is an imaginary number.

The correct choice is "7 is a solution to the original equation. The value –1 is an extraneous solution."

Answer: "7 is a solution to the original equation. The value –1 is an extraneous solution."

Step-by-step explanation:

Answer:

Both cos(17°) and sin(x°) can be represented by the ratio a/c. The angles measuring 17° and x° are complementary angles. This means x° + 17° = 90°

Therefore, x = 90-17 Since cos(17°)=sin(x°), this also shows that cos(17°)=sin( 90-17)°

this is the correct answer.

The required possibilities for the blanks as b/c, 90 degrees, (90° - 17°), and (90° - 17°). Where 17° and x° are complementary angles

The complementary angles are defined as when pairing of angles addition to 90° then they are called complementary angles.

In the given question,

Both sin(17°) and cos(x°) can be represented by ratio b/c because values of sin(17) and cos(x) are b/c.

Since 17° and x° are complementary angles, hence the value of x will be = 73 degrees. And sin(17°) = cos(x°), therefore sin(17°) = cos(90° - 17°).

Therefore, the required possibilities for the blanks as b/c, 90 degrees, (90° - 17°), and (90° - 17°).
